Problem

In an electrical calorimeter experiment, the voltage across the heater is

100.0\text{ V}

and the current is

10.0\text{ A}

. The heater is switched on for

t=700.0\text{ s}

. The room temperature is

\theta_0=10.0^\circ\text{C}

and the final temperature of the calorimeter and unknown liquid is

\theta_f=73.0^\circ\text{C}

. The mass of the empty calorimeter is

m_1=1.0\text{ kg}

and the combined mass of calorimeter and unknown liquid is

m_2=3.0\text{ kg}

. Find the specific heat capacity of the unknown liquid in proper significant figures. The specific heat capacity of the calorimeter is

3.0\times10^3\text{ J kg}^{-1}\,{}^\circ\text{C}^{-1}
